Synthyris. SCROPHULAKIACE^J. 285 



23. C APRARI A, L. ( Caprarius, relating to goats, i. e. Goat-weed. — 

 Tropical American herbs or undershrubs ; with rather small white or flesh-colored 

 flowers, on slender often geminate pedicels, in the axils of the alternate serrate 

 leaves. One species barely reaches our southern border. 



C. biflora, L. Suffruticose, 2 to 4 feet high, pubescent or glabrous : leaves oblong-lanceo- 

 late, sharply serrate above the middle: sepals linear-subulate, equalling the capsule.— 

 Key West, and S. Texas on the coast ; the glabrous form, mostly 5-androus, C. Mexlcana, 

 Moricand in DC. (Tropical shores.) 



24. SYNTHYRIS, Benth. (From air, together, and dv G ig, little door or 

 valve, the valves of the capsule long adhering below to the short placentiferous 

 axis.) — W. North American perennials, nearly related to Wulfenia of S. E. 

 Europe and the Himalayas ; but the anther-cells not confluent and seeds discoidal. 

 Leaves largely radical and petioled ; those of the simple stem or scape and the 

 bracts all alternate. Flowers small, purplish or flesh-color, in a simple spike or 

 raceme ; in summer. Stamens inserted close to the sinuses of the corolla. — DC. 

 Prodr. x. 454, & Gen. ii. 963. 



§ 1. Ovules and seeds only a pair in each cell, on a short partition : capsule 

 divaricately 2-lobed ; the cells transversely oblong : seeds with thickish margins 

 incurved at maturity : acaulescent, with naked scapes. 



S. rotundif olia. Rootstock short and creeping, bearing a tuft of cordate-orbicular doubly 

 crenate or crenate-incised leaves (glabrous or slightly hairy), and weak scapes hardly 

 exceeding the petioles (3 _or 4 inches long) : pedicels of loose short raceme longer than the 

 bluish flowers (about half inch long): sepals spatulate : corolla campanulate. — 5. reni- 

 formis, Gray, Bot. Calif, i. 571, chiefly, not Benth. — Oregon, in shady coniferous woods of 

 the Columbia and "Willamette, Nuttall, E. Hall; and probably first collected in woods N. E. 

 of Fort Vancouver by Gairdner. 



Var. cordata, a form with smaller and thicker almost simply crenate leaves of cord- 

 ate outline. — S, reniformis, var. cordata, Gray, I.e. — Gravelly hillsides, Mendocino Co., 

 California, Kellogg & Harford. 



§ 2. Ovules and usually seeds several or numerous in each cell : capsule merely 

 emarginate : seeds plane or meniscoidal, thin-edged. 



# Flowers racemose rather than spicate : leaves of the preceding section : capsule orbiculate, much 

 compressed, acute-edged. 



S. reniformis, Benth. 1. c. A span or so high : leaves orbicular-reniform, crenate and 

 crenately somewhat incised, an inch or two in diameter: surpassed by the somewhat 

 bracteate slender scape : pedicels mostly shorter than the bluish flowers : capsule trun- 

 cate-emarginate. — Wulfenia reniformis, Dougl. in Hook. Fl. ii. 102, t. 71. (Fig. 3 repre- 

 sents the capsule much too long and too turgid.) — Oregon and Washington Terr. "Grand 

 Rapids of the Columbia and Blue Mountains," Douglas. 



Var. major, Hook. Leaves of thicker texture and with multilobulate margin, the 

 lobelets crenate : raceme spiciform : capsule strongly emarginate. — Kew Jour. Bot. v. 257. 

 — Idaho. Fertile northerly slopes of snowy mountains, highlands of Nez Percez, Geyer, in 

 fruit. Porphyry Peak, Prof. Marcy, in flower. 



# # Flowers in a dense spike terminating a stouter and more or less bracteate or leafy scape or 

 stem : rootstock or caudex short, thickish, not creeping: capsule turgid, from short-oval to ellip- 

 tical, slightly emarginate or refuse. 



+- Leaves laciniately cleft or divided, all radical : corolla cylindraceous, considerably longer than 

 the calyx, deleft to the middle. 

 S. pinnatifLda, Watson. Tomentulose-pubescent and glabrate: leaves slender-peti- 

 oled, from round-reniform to oblong in circumscription, from palmately to pinnately 3-7- 

 parted or below divided, and the divisions again laciniately cleft or parted : scape spar- 

 ingly bracteate, a span high : spike narrow : flowers subsessile : corolla whitish. — Bot.
